Infinite Many solutions

Answers

Answer 1

Answer:

Infinite Many Solutions

Step-by-step explanation:

2x - y = 2 (x + 1)

2x - (-2) = 2( x + 1)

2x + 2 = 2(x + 1)

2x + 2 = 2x + 2(1) : Here I used the distributive property

2x + 2 = 2x + 2: There is infinite many solutions because if you graph this on the graph the lines will be not intercect in only one place but in an infinity amount of places because the two equations are the same in terms of Y = mx + b.

Mr. Rojas spent d dollars to go on vacation. He bought a plane ticket for $250 and stayed in a hotel for 5 nights. If the cost of the hotel room was the same each night, what expression can be used to find how much Mr. Rojas paid each night for the hotel?

Answers

Answer:

x = d/5 - $50

Step-by-step explanation:

Basiclly what this sentence is saying that the price d is equal to $250 + 5 prices of staying in a hotel for a night.

If we let "x" be the price per night then we can get the following..

d = $250 + 5x

5x = d - $250

[tex]x = \frac{d - 250}{5}[/tex]

x = d/5 - $50

Step-by-step explanation:

The required expression that represents the average of three test scores is x + y + z / 3. Option C is correct.

What is average?

The average of the values is the ratio of the total sum of values to the number of values.

Here,
The required average of three test scores,
= sum of the scores/number of scores
= x + y + z / n(x, y, z)
= x + y + z / 3

Thus, the required expression that represents the average of three test scores is x + y + z / 3. Option C is correct.

Find the value of x!!

Answers

Answer:

x = 6

Step-by-step explanation:

These two angles make a complementary angle meaning the sum of the angles will be 90°. We can use this information to make an equation to solve for x.

10x + 30 = 90 (Given)

10x = 60 (Subtract 30 on both sides)

x = 6 (Divide 10 on both sides)

DUE IN EXACTLY 5 MINUTES PLEASE HELP ME PLEASE

Answers

Answer:

The two will be at the same place in 1/5 of a minute

Step-by-step explanation:

Here, we shall substitute the value 1/2 for x on both sides of the equation

We have this as;

1000(1/5) + 20

= 200+20 = 220

secondly, we have

1,100(1/5) = 220

From the solution, we can see that both sides will be equal and the same amount of distance will have been covered

What this simply mean is that they both will be at the same place in 1/5 of a minute

A shipping crate is packed with unit cubes. The length of the crate is 4
units, the width is 2 units, and the height is 4 units. Find the volume
of the shipping crate.

Answers

Answer:

The volume of shipping crate is 32 unit cubes.

Step-by-step explanation:

Length of the crate = 4 units

Width of the crate = 2 units

Height of the crate = 4 units

Volume of shipping crate = Length * Width * Height

Volume of the crate = 4 * 2 * 4

Volume of crate = 32 unit cubes.

Hence,

The volume of shipping crate is 32 unit cubes.

Trey drove 250 miles using 9 gallons of gas. At this rate, how many gallons of gas would he need to drive 275 miles?

Answers

Answer:

10 gallons of gas.

Step-by-step explanation:

250/9 = how many miles 1 gallon of gas will take

250/9 = 27.78

1 gallon of gas = 27.78 miles

275/27.78 = 9.90 gallons

9.90 gallons round up to 10 gallons

Therefore, Trey would need 10 gallons of gas to drive 275 miles.
